The usage method of environmentally friendly penetrating agent JFC varies by application field. It is typically added directly to the working solution at a dosage of 0.1% to 5%, and can achieve excellent penetration and wetting effects at room temperature to 60°C and within a wide pH range.

Detailed Description

Environmentally friendly penetrating agent JFC (fatty alcohol polyoxyethylene ether, CAS number: 68439-50-9) is a nonionic surfactant. It appears as a colorless to slightly yellow transparent liquid, easily soluble in water, with an HLB value of 11 to 13 and strong penetrating power (standard canvas sinking method ≤5 seconds). In actual use, add the product proportionally directly to the treatment bath or formulation according to the specific process and stir evenly. Its resistance to acid, alkali, and hard water enables it to maintain high performance under a wide range of process conditions.

This product can be added directly as a neat solution by metering, or pre-diluted with water to a 10% to 20% solution for accurate metering and rapid dispersion. Since the cloud point is approximately 40 to 50°C, it is recommended to use at room temperature to 60°C for optimal penetration. In processes requiring high temperature treatment (e.g., cotton fabric scouring), it can be compounded with anionic surfactants to improve temperature resistance. The product has good compatibility and can be compounded with anionic, cationic, and other nonionic surfactants for better synergistic effects.

Usage Methods by Application Field

Textile Printing and Dyeing Pretreatment

In the desizing, scouring, and bleaching processes of cotton, linen, synthetic fibers, and their blends, add 0.1% to 0.5% of the working liquid weight. Add directly to the desizing or scouring liquid and treat at 60 to 100°C to quickly wet the fibers and allow the working liquid to penetrate evenly into the yarn interior. Its low-foam properties are especially suitable for high-speed overflow dyeing machines, preventing fabric jamming and circulation pump cavitation caused by foam.

Leather Processing

Soaking step: Add 0.2% to 0.5% of the raw hide weight, used together with soda ash or soaking enzymes. Soak at room temperature to accelerate moisture penetration and shorten soaking time. Degreasing step: Add 0.5% to 1.0% of the hide weight, used together with alkaline auxiliaries (e.g., soda ash, degreasing agent) and treat at 35 to 40°C to effectively emulsify and remove natural fats.

Industrial Hard Surface Cleaning

In water-based metal cleaning agent formulations, JFC is typically used as a penetration-enhancing component. The recommended addition amount is 1% to 5% of the total formulation weight, compounded with nonionic or anionic main cleaning agents. In immersion or spray cleaning at room temperature to 60°C, it can penetrate deep into the gaps between oil stains and substrate, improving oil removal efficiency.

Paper Deinking

In the waste paper deinking process, add 0.1% to 0.3% of the dry pulp weight, together with deinking agents (such as NaOH, sodium silicate, H₂O₂, etc.) into the pulper, and act at 40 to 55°C to quickly wet the ink and promote its detachment from the fiber surface.

Pesticide Formulations

For wettable powder (WP): Use as a wetting and dispersing auxiliary, add 1% to 3% of the total formulation weight, mixed into the material before jet milling. For emulsifiable concentrate (EC): Use as a co-emulsifier, add 2% to 5%, compounded with the main emulsifier to improve the spontaneous dispersibility and dilution stability of the emulsion.

Waterborne Coatings and Inks

Use as a wetting and dispersing auxiliary, add 0.1% to 0.5% of the total formulation weight during the pigment dispersion stage to quickly wet the pigment and filler surfaces, aid in deagglomeration, and reduce the dynamic surface tension of the system, improving substrate wetting and leveling, and preventing cratering and floating.

Application Recommendations

  • Addition Method: Can be added directly as a neat solution by metering, or it is recommended to pre-dilute with process water to a 10% to 20% concentration before adding to the working bath for rapid and uniform dispersion.
  • Temperature Control: The cloud point is 40 to 50°C. Best effects are achieved at room temperature to 60°C. For high-temperature processes (>70°C), it is recommended to use with nonionic/anionic composite systems.
  • Compatibility: Has good compatibility with anionic, cationic, amphoteric, and other nonionic surfactants, serving as a synergistic component in multifunctional auxiliary formulations.
  • Storage: Store sealed in a cool, dry place at 5 to 40°C. Check product appearance and properties before use after long-term storage.

Precautions

  • This product causes skin irritation (H315) and serious eye irritation (H319). Must wear chemical safety protective gloves, goggles, and protective clothing during operation.
  • Avoid direct discharge of untreated waste liquid into sewers or natural water bodies to prevent long-term harm to aquatic ecosystems (H412).
  • In case of skin contact, rinse immediately with plenty of water and soap. If splashed into eyes, rinse continuously with water for at least 15 minutes and seek medical attention.
  • The above recommended dosages are general industry reference ranges. The optimal dosage should be determined through small-scale tests based on actual process conditions and raw material characteristics.
